Welcome to Part 7 inBruce Music‘s Blog Series On Music Theory. This part is a brief recap of the main points covered in the first 6 parts. Be sure to check out those previous instalments if there’s anything here you’re unsure of.

The 12 notes in music – C C#/Db D D#/Eb E F F#/Gb G G#/Ab A A#/Bb B

Distance between each note = semitone (one fret)

Two semitones = A Tone.

Major scale formula = T T S T T T S

Minor scale formula = T S T T S T T

Pairs of relative Majors/Minors = A Major scale and the minor scale starting from the Major Scale’s 6th note = relative major/minor pairing

Chords are formed of a Root, 3rd and 5th. Root gives the chord its name, 3rd determines if it’s Major or Minor, and 5th solidifies the chord

Formula for chords in a major key (One chord starting from each step of the major scale) = IMaj IImin IIImin IVmaj Vmaj VImin VIIdim
